Can you use Flonase when you have glaucoma?

As you probably know, the body can absorb steroids into the blood stream. In some patients, this can raise the intraocular pressure (IOP). Flonase is a nasal steroid spray that can raise intracocular pressure. While I cannot speak in absolutes about whether you can use Flonase without knowing your history, I would strongly recommend that you monitor your IOP while using the product. Many glaucoma patients can safely use Flonase without any damaging side effects, but I would have your pressure checked in the first few weeks after starting this medication. If you have a history of pressure elevations associated with steroid usage, I would certainly proceed with great caution.
